Abstract: PURPOSE:To suppress pressure fluctuation in a room which is an object of ventilation accompanying a change in the volume of air blast by relating rationally the change in passing air blast by means of a ventilation amount change device with the room pressure control by means of a room pressure controller. CONSTITUTION:A ventilation amount change means 11 which changes the amount Q of air passing through a room 3 and a room pressure regulating means 16 which adjusts the amounts of air supply and air exhaust in the room are provided in a forced ventilation air passage for the room 3 which is an object of ventilation. Further, a room pressure controller 18 controls automatically a room pressure regulating means 16 so that a detected room pressure is maintained at a set value based on the room pressure detection for the room 3. And a room pressure stabilizing control means 13A controls a ventilation amount change means 11 when the ventilation amount is changed by the ventilation amount change means 11, so that the variation per unit time of ventilation amount Q is restricted to a value which suppresses the room pressure fluctuation accompanying the variation of ventilation amount in a set allowable range of variation by means of the room pressure controller 18. As a result, it is possible to prevent accidental invasion into a clean room of polluted air, etc. due to variation of room pressure.

Filed: 1986-03-18
Abstract: PURPOSE:To improve the deterioration in an error ratio by providing a variable phase shifter to use a thermo-sensitive element between the second hybrid circuit and the second or first detector and compensating the dislocation of the phase difference in two reproducing carriers applied to the first and second detectors by the variable phase shifter. CONSTITUTION:After a reproducing carrier generated by a carrier reproducing circuit CR7 is branched to a reproducing carrier having a 90 deg. phase difference by a 90 deg. hybrid circuit HYB6, the carrier is applied through a variable phase shifter 8 and a fixing delaying circuit 9 to a detector 3 and a detector 2. Since the phase of the reproducing carrier to input to the detector 3 is dislocated by the temperature change, the dislocation is compensated by the variable phase shifter 8. Namely, when an ambient temperature T is changed by DELTAT only and the resistance value of a thermo-sensitive element TH is changed by DELTARth only, a capacity value Co of a diode is changed by DELTACo only, and the phase of the reproducing carrier added from 90 deg. HYB6 to the detecting deice 3 is shifted by DELTAphi only. Then, the phase dislocation from 90 deg. is improved and the deterioration in a code error ratio is improved.

Title: Touch sensor
Inventor: GOTOU NORIO

Filed: 1979-05-18
Abstract: PURPOSE: To obtain a touch sensor input as two-dimensional position information by making use of the change of the propagation of an elastic surface wave depending upon the state of a propagation path.  
     CONSTITUTION: Elastic-wave exciting transducers 6 and 7 are arranged at right angles and detection transducer 10 is arranged being bent stepwise on the slant face to transducers 6 and 7. The output of 1st transducer 6 propagates propagation paths 6a, 6b and 6c toward detection transducer 10. The output of 2nd transducer 7 propagates propagation paths 7a, 7b and 7c toward detection transducer 10. Therefore, detection trasducer 10 obtains pulses with delay time corresponding to a difference in propagation path. When one point in an area encircled with transducers is pushed by a finger, the propagation of a corresponding path is inhibited and pulse detection is disabled. The position can therefore be found.
